Infants show stability of goal-directed imitation

Elena Sakkalou, Kate Ellis-Davies, Nia C. Fowler, Elma E. Hilbrink, Merideth Gattis
2013 Journal of Experimental Child Psychology  
We reasoned that if selective imitation of goal-directed actions reflects understanding of intentions, infants should demonstrate stability across perceptually and causally dissimilar imitation tasks.  ...  Infants who selectively imitated goal-directed actions in an object-cued task at 13 months also selectively imitated goal-directed actions in a vocal-cued task at 14 months.  ...  We thank Barbara Carotti for her help with coding of the data and Sylwia Matuszewska for her help during the monthly participant meetings.  ...

From motion capture to action capture

Bernhard Jung, Heni Ben Amor, Guido Heumer, Matthias Weber
2006 Proceedings of the ACM symposium on Virtual reality software and technology - VRST '06  
The idea of action capture is inspired by human imitation learning; related methods have been investigated for a longer time in robotics.  ...  As an advantage, the learned actions can often be naturally applied to varying situations, thus avoiding retargetting problems of motion capture.  ...  As in motion capture, the goal of her imitation learning approach consists of the humanoid agents repeating the movements of the human trainer.  ...

Learning from Humans [chapter]

Aude G. Billard, Sylvain Calinon, Rüdiger Dillmann
2016 Springer Handbook of Robotics  
The field is best known as robot programming by demonstration, robot learning from/by demonstration, apprenticeship learning and imitation learning.  ...  We then summarize the various approaches taken to solve four main questions: when, what, who and when to imitate.  ...  Based on the subsymbolic goal and constraint descriptions, the robot can reason to adapt the strategy to changes in object location, obstacle occurrence, and varying start configurations.  ...

Learning nonparametric policies by imitation

D.B. Grimes, R.P.N. Rao
2008 2008 IEEE/RSJ International Conference on Intelligent Robots and Systems  
A long cherished goal in artificial intelligence has been the ability to endow a robot with the capacity to learn and generalize skills from watching a human teacher.  ...  Such an ability to learn by imitation has remained hard to achieve due to a number of factors, including the problem of learning in high-dimensional spaces and the problem of uncertainty.  ...  The motion was learned via imitating by observing a human demonstrator perform the desired motion. Using an inference-based motion planning algorithm a stable imitative motion is obtained.  ...

Review of the techniques used in motor‐cognitive human‐robot skill transfer

Yuan Guan, Ning Wang, Chenguang Yang
2021 Cognitive Computation and Systems  
Based on the idea of establishing a generic or specialised robot skill library, robots are expected to autonomously reason about the needs for using skills and plan compound movements according to sensory  ...  Skill transfer methods that are commonly used at present, such as learning from demonstrated (LfD) or imitation learning, endow the robot with the expert's lowlevel motor and high-level decision-making  ...  Imitation and emulation as two common imitative behaviours are the motion/action copier and goal/final effect copier, respectively.  ...
